Finds, when one cancels the insurance on? (9)
I believe the answer is:
discovers
'finds' is the definition.
('discover' can be a synonym of 'find')
'one cancels the insurance on?' is the wordplay.
I cannot really see how this works, but
'one' could be 'i' (Roman numeral) and 'i' is located in the answer.
'insurance' could be 'cover' (I've seen this before) and 'cover' is located in the answer.
This explanation may well be incorrect...
'when' acts as a link.
Can you help me to learn more?
(Another definition for discovers that I've seen is " Unearths".)
